sizeof("MAXCPU") being used to calculate a string length rather than
something more reasonable such as sizeof("32"). This shouldn't have
caused any ill effect until we run on machines with 1000000 or more
cpus.
the vap ioctl. This means that the parent interface should hopefully be up
before we return to userland, it does not depend on the parent init succeeding,
just that it was run.
This fixes wpa_supplicant with ndis and USB where the parent interfaces can be
slow to init.
- Restructure selscan() and selrescan() to avoid producing extra selfps
when we have a fd in multiple sets. As described below multiple selfps
may still exist for other reasons.
- Make selrescan() tolerate multiple selfds for a given descriptor
set since sockets use two selinfos per fd. If an event on each selinfo
fires selrescan() will see the descriptor twice. This could result in
select() returning 2x the number of fds actually existing in fd sets.

Now that make_dev() doesn't require unit numbers to be unique, there is
no need to use an unrhdr here to generate the numbers. Remove the entire
init-routine, because it is optional.
pointers to the callout handler just before and just after the callout
it invoked. I attempted to do this in a manner congruent to tracing in
Solaris's callout mechanism, but couldn't quite use the same names due
to convention and syntax differences.
Example DTrace script to generate a distribution graph of callout
execution times:
callout_execute:::callout_start
{
self->cstart = timestamp;
}
callout_execute:::callout_end
{
@length = quantize(timestamp - self->cstart);
}

Change "smaller files" to "split files" which is more in line
with what "-b" actually does.

- Remove GIANT_REQUIRED from vmtotal() (everything in this routine already

make KERNFAST=blah buildkernel
is now a short cut for
make KERNCONF=blah -DKERNFAST buildkernel
This change works for all kernel config files not named "1". I did
that to make sure that
make -DKERNFAST buildkernel
remains the same as
make -DKERNFAST KERNCONF=GENERIC buildkernel
rather than trying to build and configure "1". I've never seen a
kernel config file named "1," so I think this is a good compromise.
This should be a bit useful for users who look at the manpage and
then try to copy data CD-ROM disks using dd. A lot of us know
that bs=2048 is required, but it still manages to cause a bit of
grief to those who haven't heard about it.
